General Information
CAEN RFID easy2log©RT0005 is a low cost, semi-passive UHF logger tag that allows to monitor temperature sensitive
products like perishable foods and pharmaceuticals, during transportation and storage. The combination of the high
resolution sensor, the large memory size and the standard RFID interface permits to realize effective track and trace
solutions for the cold-chain.
The RT0005 can be used with standard UHF RFID readers available on the market without requiring any additional
equipment thanks to its compatibility with the EPCGlobal C1G2 and ISO18000-6C standards.
The tag can be configured to store temperature samples in intervals from 1 second to 18 hours in the internal memory
that can contain up to 3,958 samples. The user can define up to 16 temperature ranges with independent threshold
alarms for a very accurate control of the temperature excursions. The tag can be started either using a button or via
standard RFID commands.
The tag is also able to calculate the Mean Kinetic Temperature and user configurable remaining shelf life time as well
as generate alarms in case these parameters exceeded user defined thresholds.
The RT0005 RFID logger can be used for multiple shipments thanks to the long battery life and the reset function thus
allowing to reduce the total cost of the solution and anticipate the ROI.

In the Mod. RT0005ET the sensor is placed on an external probe so it is possible to measure temperature even inside a
shielded box where the RFID field cannot get through.

Operating states
easy2log©RT0005 tag behaves according to the following operating states:
Stand-by. Stand-by is the starting state of the tag. In this state the tag respond to reader interrogations, the log
memory is empty and the internal clock is not started. This is the lower power consumption state.
Idle. The tag is in Idle state when the internal clock is running, the memory is empty and the tag is waiting for a start
logging command. The start command can be issued either by an RFID command or by the button.
Active. The tag enters in Active state after having received the start logging command, in this state the tag wakes up at
defined intervals in order to acquire temperature samples and, eventually, it stores those samples inside the log
memory.
Sleep. The tag enters in the Sleep state at the end of a logging activity. Differently from the Idle state, in Sleep state the
tag's log memory is not empty and it is retained until a reset command is issued.
